Frequently Asked Questions
Q1: What is the main function of FPD1000AS?
A: It is a medium‑power GaAs pHEMT RF transistor, used as high‑linearity driver or power amplifier for wireless systems up to 5 GHz.
Q2: What output power can FPD1000AS deliver?
A: Typical P1dB output power is +31 dBm (1.26 W), with 15 dB gain at 1.8 GHz.
Q3: What package is FPD1000AS?
A: 3‑pin SOT‑89 SMT package with exposed metal tab for PCB thermal grounding.
Q4: How to get datasheets, S‑parameters or volume quotes?
A: Documents, stock check and bulk pricing are available via our Quick Inquiry form. We will reply within 24 hours.
Q5: Are there direct drop‑in alternatives for FPD1000AS?
A: No pin‑to‑pin direct replacement. Similar performance can be found in other Filtronic SOT‑89 pHEMTs. Contact our team for substitution suggestions based on your frequency and power requirements.
Q6: What does suffix “AS” mean in FPD1000AS?
A: “AS” denotes SOT‑89 surface‑mount package for FPD1000 series. Different suffixes mean different packages; always verify full part number before ordering.
Q7: Why do search results show TO‑59 package for FPD1000AS?
A: FPD1000AS is SOT‑89 only. TO‑59 belongs to other suffix variants (FPD1000AQ / FPD1000ASSQ). They are not pin‑compatible and cannot be swapped directly.
Q8: What are key operating precautions?
A: This is depletion‑mode pHEMT. Apply negative gate‑source bias before drain voltage. Do not exceed maximum Vds rating of 8 V DC.
Q9: What’s the difference between FPD1000AS and other FPD1000 variants?
A: FPD1000AS is SOT‑89 SMT version. Other variants use different packages or gate widths, with different power and thermal performance. Refer to official datasheet for each model.
Q10: Can FPD1000AS work above 5 GHz?
A: Specified for DC‑5 GHz. Performance degrades sharply beyond 5 GHz; operation above 5 GHz is not recommended.
